Inasmuch as the gripping and 10 question-through a considerable size range, thus cushioning action is by pressure and not by an avoiding the necessity of fitting the box to the exact fit of the parts, it will be apparent that a. contents, or carrying in stock a large assortment considerable variation in length, width and thick of box sizes. ness of the object packed can be accommodated Further purposes are the provision of such a within any given size of box.

The outer casing, and an inner element which serves natural resiliency of the material tends to spring the several purposes of inner container; spacer, the clamping flaps 6 up into the partially open 20 clamp, cushion, and added protection for the conposition illustrated in Fig. 1, so that in eifect the tained object when the outer covering is closed. fold line l5 becomes a compression spring in the To the accomplishment of the foregoing and closed container, Fig. 2 tending to cause a spread related ends, said invention, then, consists of the between the panels 1 and wings 8, and thus giving means hereinafter fully described and particularly both a clamping and a cushioningaetion. 25 pointed out in the claims.

It will also be evident from the foregoing description that although a complete measure of security'is aiforded by'having clamping flaps both at sides and at ends, the principles of the invention could be applied by the use of only two clamping flaps. It will also be apparent that although the box illustrated as an embodiment of ig g gii gg flaps comprise h my invention is of conventional rectangular form, wardly directed panels 1 and the top wings 8 that the principles are susceptible of application nected thereto along fold lines l5.

I therefore particularly point out and distinctly claim as my invention:

1. A package consisting of inner and outer containers, the inner comprising a plurality of elements Z-shaped in cross section, with a bottom common to all the Z-shaped elements composed of the bottom bar of each Z, opposite panels inclined inwardly over said bottom, and top flanges outwardly directed over said inclined panels, and an outer container of internal base area to receive said inner container snugly and of internal heightgreater than three times the thickness of the inner container material and less than the width of an inclined panel.
